Question

verify that —
-1 + (-2/3 + -3/4) = (-1 + -2/3) + -3/4​

Answer 1

Given:

$- 1 + ( \frac{ - 2}{3} + ( - \frac{3}{4} ) = ( - 1 + ( - \frac{2}{3} ) + ( - \frac{3}{4}$

$- 1 - \frac{2}{3} - \frac{3}{4} = - 1 - \frac{2}{3} - \frac{3}{4}$

$\frac{ - 12 - 8 - 12}{12} = \frac{ - 12 - 8 - 12}{12}$

$- \frac{32}{12} = - \frac{32}{12}$

therefore LHS= RHS
